Inductive sensor 2020 mount

thingiverse

The sensor size is a standard 12mm inductive Z-home sensor that fits perfectly on the 2020 frame. The distance from the probe center to its edge is precisely 13mm. For assembly, you will need two M3x10 DIN 963 screws and two M3 T nuts. The LJ12A3-4-Z/BX sensor itself completes the package. One notable feature of this sensor is that it produces an inverted signal. To correct for this, make sure to modify your Marlin firmware's Configuration.h file by setting Z_MIN_ENDSTOP_INVERTING to true. Additionally, define Z_HOME_BUMP_MM as 2 in the Configuration_adv.h file. This setup has been tested on both MKS GEN L and SKR 1.3 boards without requiring any additional hardware. The sensor's wiring is straightforward: Red (or brown) for +5v, Blue for Gnd, and Black for S (signal).
